It’s hard to believe it’s been nearly two and a half years since we first met Krysten Ritter’s Jessica Jones in Marvel’s television universe. Although we saw her as just one of the many super-powered characters packed into Marvel’s The Defenders last year, despite all she’s been through not much has changed with the private investigator. That same angry, tough, bitter, and unhappy anti-hero is the same person we meet at the beginning and at the end of the second season of Marvel’s Jessica Jones, now appearing on Netflix. For fans of the fringe of the Marvel superhero world where little fun is to be had, Ritter’s gritty heroine stands alongside The Punisher (our favorite superhero series last year). Yet despite its heavy dramatic component, it’s very much a superhero show, providing a complete picture of the downside of possessing superhero powers created by chemicals in a lab–a key fact of life for so many Marvel creations, including The Hulk, Deadpool, Luke Cage, the Fantastic Four, the Winter Soldier, etc. For those viewers that thought Jessica Jones’s first season was the best TV had to offer, good luck comparing which is best after watching the second season.

But it’s not really Jessica who shines in Season 2 as much as the supporting characters, and the series doesn’t really reach its stride until Episode 7. The real standout for Season 2 is a new super-powered character created by the same mad scientists that created Jessica Jones, actor Janet McTeer’s new complex antagonist Alisa. Alisa is a driven, unstoppable human machine attached to a fantastic, layered core. Alisa is older and wiser and far more powerful than Jessica or anyone else we’ve seen from the Netflix Marvel realm. Two scenes with Alisa playing the piano really reveal what viewers are in for (and the cast of characters is up against). Unfortunately for Alisa and everyone that she touches, she’s been pushed to the extremes, resulting in a decisively volatile foe. As with Marvel’s Killmonger in this season’s big screen movie Black Panther, calling Alisa the villain of the show omits much about the character. A cold-blooded killer? Sure. But even the worst can still have hope for redemption, especially if what made them bad in the first place was never their fault. Or can it?

Right along with Alisa, Jessica’s step-sister Trish “Patsy” Walker–Jessica’s rather bland supporter and confidante in Season 1–really leaps into action in a breakaway performance that aims toward Linda Hamilton’s tough-as-nails heroine in Terminator 2: Judgment Day. Credit the acting range required of actor Rachael Taylor this time around and a stellar character arc created for her by the writing team of Melissa Rosenberg, Jack Kenny, Aïda Mashaka Croal, Gabe Fonseca, Lisa Randolph, Jamie King, Raelle Tucker, Hillie Hicks, Jr., Jenny Klein, and Jesse Harris. Viewers may want to strangle Trish by the halfway mark in the season, but just wait–she only gets in deeper as the series progresses.
